Step By Step Forums Guide or Manual

Is there a step by step guide, 100% on setting up the site wide and group forums? I love BuddyPress but I find myself using other community software because every time I install buddypress I get stuck at the Forums setup.

It seems to be getting easier and the installations are better BUT once again I can not get my forum to work.

Is there a GUIDE or MANUAL to install these groups / forums that explains exactly what needs to be done?
